Snake bites

• Didi Gregorius (elbow) was scheduled to begin a rehab assignment with Triple-A Reno on Monday as the team's designated hitter, but a rainout postponed the game.

• After serving as the team's DH for three games, Cody Ross (calf) is scheduled to play five innings in the outfield for Class A Advanced Visalia on Monday. The game will mark the first time the outfielder has played defense since Spring Training. If there are no setbacks, Ross could rejoin the D-backs as soon as Friday.

• The D-backs will wait another two weeks before testing the elbow of injured center fielder Adam Eaton, who began hitting on Thursday.
